n such cover.

The various wires leading to the plates 1: are

conveniently plaited or bound together to form a cable the wires to the spidersfand 9 being let loose to fa ilitate their connection. The casing a may Lt. closed at the back by a metal cover p having lugs q or brackets for securing the casing in position, the cable and loose wires being passed throughan aperture The apparatus for the driver, which a paratus may for instance be fixed to the ashboard of a carriage, comprises a casing r, Figs. 4 and 6, behind the glazed front s of which is a dial 6 having eight holes it through which rotrudc eight small incandescent electric amps v. The lamps v-are preferably llattcned as seen in Fig. 6 their rear portion being opaque as shown by the thick line and their front or llattened portion having indications corresponding to those given above. Each lamp 1: is screwed into a hole w in a non-conducting disk fixed in the casing r and is ada ted to make contact with a spring y in .t e side wall of the hole w and with a ring z 'iixcd to the rear face of the disk As scj'enjn Figs. 5 and 6 the s rings g also are lined tot ie rear face of the t isk and are bent over and pioject into the holes .10 so that upon the hin'ips -v being screwed in, the metal screw sleeves 1 around the plug parts of the lamps and tonstituting one. terminal thereof in knownhuii'incr, make contact with the projecting s htmgs y and when the lamp is screwed right liomecontacts .2 upon the ends of the plug portil iisgiiake contact with the ring 2. To the rear face of the disk :0? is also connected a hell preferably of the repeating typo in which the h'anm-tcr is carried by the trcmbler. This bcll comprises a gong 3 fixed to a frame 4 which in turn is secured to a rmg 5 conveniently li.\'cd to the disk as byscrews ti and distance slccvc pieces 7. The armature or tremblcr 8 carrying the hammer being vibrated by the coil 9 makcs and breaks contact with a spring H) but ll.- bcll may be of any other known tvpc. 'll:. electrical connections are seen in Fig. 7. One terminal ll of tho l'u-ll l.-' connected by a flexible wire IL! with onc ol thc aforesaid .contact plates 7: on

button d is pressed in the passengers compartment one arm of each spider viz an arm 6 and an arm c are tossed on to one of the 5 current then flows from the battery 15 through wire 17 one s iiderf to the contact plate 1' through the terrible connection 18 to the side contact y of the correspondin lamp through the latter to the ring z an then-:zc by wire 16 to the batt-cry thereby lighting the correspondin lam v and signaling to the driver the esires order. At the same time current flows from the contact plate k through the other spider and by wire 12 the bell terminal 11 througtremb er 8 to contact IO-t-henco by wire 20 to the coil 9 and thence by wire 14 to the opposite pole of the battery. Itwt ll be understood that a rear cover might be provided for theorising r but in the ordinary wa the gon 3 is sufficient cover in itself. {rugs sinner to the lugs g are rovided on the casing r for fixing it to say t e dash board of. a motor car. A

' The present improvements are not limited to the employment of an particular kind of lamp or switch nor is it. imited to the mute. ber shown but the arrangement of the parts hereinbefore described constitutes a neat and cheap apparatus not likely to get out of. order and motor road vehicle. Assurrung the casings. be made circular as shown this not only pro-- duces a much smaller and more convenient articularly suited for use upon a 91.,

combination with a switch device COUIPTiSlIlfi a casing, a plurality of contact plates one contact plate having a se aratedesignation. or ordcr, two series of ra ial spring arms or blades, and means for causing said radial spring arms to contact with said contact platcs. of a source of electricity, an audible signaling device, an electric circuit for said audible.signaling device controlled by the said sw-itch device, a plurality of electric lamps. a casihg to contain said lamps each lamp havin; a separate designation or order and a plurality of electric circuits, one for each lamp, controlled by the said switch de vice substantially as set forth.-

2. In an electric signaling apparatus for communicating instructions from a passenger to the driver of.a vehicle the combination with a switch device comprising a casing,\'

a plurality of contact plates in said casing, tiro series of radial spring arms or blades to form a )lur'ality of pairs and a plurality of pushes l or causing pairs ofsaid spring arms to contact with said contact plates each of said pushes having a se )arat-e designation or order, of a source of electricity, an audible signaling device, an clecric circuit for said audible signaling device controlled by the said switch device, a plurality of electric lamps each lamp having a scpara te designation or order, a casim to contain said lamps, and a plurality of electric circuits, one for each lamp, controlled by the said switch de vice substantially as set forth.

3. In an electric signaling apparatus for communicating instructions from a passengcr to the driver of a vehicle, the combination with a switch device comprising :1 cas--. ing, a plurality of contact plates in said casing, two series of radial spring arms or blades to form a plurality of pairs, a blade of one series and a blade of the other series forming a pair and adapted to contact with a. contact plate, and a plurality of pushes for causing pairs of said spring arms to contact with said contact plates, each of said pushes having a. separate designation or order, of a source of electricity, a casing, an audible signaling device, an electric circuit for said audible si naling device controlled by the said switc- 1 device, a plurality of-electric lamps, each lamp having a separate desi nation or order, one contact of each of said amps connected to a contact plate, the other contact of each of said lamps connected by a. common conductor to one pole of the source of electricity, the said contact plate and the conductor from the. other pole of the battery connected 'forations in said dis to the said switch device, substantially as set forth.

4. In an electric signaling apparatus for communicating instructions from a passenger to the driver of the vehicle, a visual signaling device comprising a casing, an insulator disk in said casing, a circular series of contact in each of said"perforations, a plurality of electric lamps, each having a separate designation or order and fitting into one of said perforations, and a contact ring fixed perforations in said disk, a lamp terminal to the rear of said disk and common to all of the other terminals of the lamps, substantially as set forth.

5. In an electric signaling apparatus for communicating instructions from a paserb ger to the driver of the vehicle, a; visual signaling device comprising a casing,'an insulator disk in said casm a circular series of peri, a lamp terminal contact in each of said perforations, a plurality of electric lam )s, each having a separate des ignation or order and fitting into one of said perforations, a contact ring fixed to the rear of said disk and common to all of the other terminals of the lamps, and an audible signaling device arranged at the rear of and concent-tic with the disk supporting the lamps, said signaling device being in circuit with as "h of said lamps, substantially as set forth. .in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
